I'm consistently amazed at the never-ending variety of inventions people come up with to solve everyday problems and make life just a little bit easier. (Favorite example: pocket-sized wipes that remove wine stains from your teeth with just one swipe.) I, for one, am not creative enough to actually invent anything at all, but I do have a knack for hunting down those inventive products — and then shouting about them from the rooftops. And these things under-$30 on Amazon? They're so brilliant, I'm going to recommend them to all my friends. And now you, of course.

Like the wine wipes mentioned above, all these products will make you say, "Wow! There's a thing for that!" And that's a very satisfying feeling because it means the product actually has a practical use — perfect if you're looking to spend money on products that won't just sit on a shelf.

And speaking of spending money, none of these products breaks the $30-dollar ceiling, so you can still shell out for extra guac at lunch today. So if you're ready to tell everyone you know about some amazing and inventive finds — or just, you know, low-key mention them to your friends — I've got you covered.
